I am trying to learn BOUML/UML on Fedora 20, where BOUML v4.21 is in official repository. After 6 hours playing with BOUML, creating various blocks, FSMs and other stuff I had saved project and fall asleep.

Next day I tried to open project but following error does not allow me to continue:

/home/name/BOUMLproject/128130 cannot be opened for read, retry?

I found out that the project directory is missing the file "128130" and it only contains "128130.diagram" file (and other files with different names).

Can anybody help me please to reopen the project? I would appreciate it a lot.

Sorry but I do not manage anymore the versions before the 5.0, however I do not remember a bug in the save in general (independently of the Linux distribution) c.f http://www.bouml.fr/historic_old.html. Did you saved your project while your disk was full ?

A file named by a number without an extension represent a bouml package, if you loose a package-file you loose at the same time all its sub elements and their sub elements etc, so you can modify the file referencing 128130 (without extension) to stop to reference it but you will have other errors because 128130 sub elements and their sub elements will not be created too
